Question

【題目】—How long have you been going to work on foot?

—Since last month when I ________ from a heart attack.

A.recoveredB.have recovered

C.was recoveringD.would recover

Answer 1

【答案】A

【解析】

考查時(shí)態(tài)。句意：——你步行上班已經(jīng)多長時(shí)間了?——自上個(gè)月我心臟病康復(fù)開始。last month是過去的的時(shí)間點(diǎn)，應(yīng)該與過去時(shí)連用，when引導(dǎo)定語從句，指代last month，指上個(gè)月我從心臟病康復(fù)。用一般過去時(shí)。故選A。
